The 1992 to 1996 phase of the conflict in Afghanistan (1978–present) began after the resignation of the communist President Mohammad Najibullah. The post-communist Islamic State of Afghanistan was established by the Peshawar Accord, a peace and power-sharing agreement under which all the Afghan parties were united in April 1992, except for the Hezb-e Islami of Gulbuddin Hekmatyar. Hekmatyar started a bombardment campaign against the capital city Kabul which marked the beginning of this new phase in the war. In direct contrast to the Soviet era, the countryside witnessed relative calm during that period while major cities such as Kabul, Mazar-e Sharif and Kandahar witnessed violent fighting.
